Sorry...that's Blu-Ray. HD DVD uses VC1 almost completely and is a much more efficient codec taking up 1/3 the space (sometimes less) than MPEG2 does.

Sorry, I thought I saw you on the AVS forums with regards to making red laser DVDs of HD content, playable in HD-A1 using Ulead's software. Isn't that how you did your Trailer HD DVD?
In the near future, hopefully the homebrew community will be able to run out DVD-Rs / DVD+R DLs with H264 & VC-1 video, but for the short term, HD DVD is stuck with MPEG-2, although at least that works (I understand Blu-ray and Ulead don't)
